In a Facebook post (via Collider), Gunn revealed that, while he was hard at work on Vol. 2, he carved out some time to help Strange director Scott Derrickson by shooting a series of potential Stan Lee cameos for the rookie Marvel film starring Benedict Cumberbatch. Gunn posted this image and caption:

Doing my pal Scott Derrickson a solid and shooting Stan Lee's cameo for Doctor Strange at the same time I was shooting…

“Doing my pal Scott Derrickson a solid and shooting Stan Lee’s cameo for Doctor Strange at the same time I was shooting some stunt work with Zoe Saldana — I run between sets on one soundstage. Stan laughing at The Doors of Perception was what ended up in the film, but we shot other options, such as – – Stan reading a book and leaning into the guy next to him, saying, “Do you know what excelsior means?” – Stan throwing his head back and laughing as hard as he can, yelling, “I’m laughing for no reason! I’m totally crazy!” – And, my favorite, Stan laughing hysterically at a Garfield book, hooting, “He HATES Mondays but he LOVES lasagna!” Supposedly that one was in the film for a while, but it ended up being too long for the scene.

Happy Tuesday!”

As if that weren’t enough work for a man Lee’s age, the superhero legend has also (per Collider) reportedly already filmed some cameos for future use in the studio’s upcoming blockbusters — likely for Spider-Man: Homecoming and Thor: Ragnarok. Whether he pops up in Infinity War is presently unknown, though we’ll bet we haven’t heard the last “Excelsior!” from the Marvel icon.
